DEVICE FOR CQNVERTING MOTiON.

UE ECIFICATION forming part of Letters Patent No. 323,546, dated August 4, 1885.

(No model.)

To all whom it may concern:

Be it known that 1, CHARLES H. TUCK- W001), of Janesvillc, in the county of Rock and State of \Visconsin, have invented certain new and useful Improvements in Devices for Converting Motion; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art-to which it appertains to make and use the same.

My invention relates to an improvement in devices for converting motion, the object of the same being to provide a simple, efficient, and durable device for converting reciprocating into rotary motion, which shall be particularlyadaptcd to use with wind-wheels; and with these ends in view my invention consists in a pair of spring-actuated grips adapted to be forced into contact with the opposite faces of an annular groove by means of a reciprocating slide suitably connected therewith.

Myinvcntion further consists in certain fea turcs of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

in the accompanying drawings, Figure 1 is a view of the device in front elevation with slide in elevated adjustment; Fig. 2, the same with slide depressed; Fig. 3, a front view of the grooved wheel with grips in position; Fig. 4, a plan view; and Figs. 5, G, and 7, detached views of the grip, gripbperating lever, and one of the concentric arms, respectively.

A indicates a main shalt journaled horizontally in suitable bearings, a a, at the front and rear, respectively. The bearings (I are formed in standards or brackets B, rigidly secured to a suitable base, (3, which may consist of a platform made for the particular purpose, or may be a floor or frame of abuilding adapted to the purpose. The standard B conveniently projects above the bearing and forms a support for the slide D, which is supposed to be reciprocated by the crank-rod of awind-wheel or other power which it may be found desirable to employ. The slide D is secured in a suitable groove, d, formed on the upper end of the standard, and is provided with perfo rated lugs 11 on its opposite sides for the attachmentotlthc upper ends of the connectingrods E. The front end of the shaft A is pro vided with a wheel, 1*, rigidly secured there on, preferably located immediately in front of the standard B. The face of the wheel F is provided with an annular groove, f. Two grips, G, each consisting of two half-sections, are adapted to fit within the groove f and have an easy-sliding motion therein, their outer and inner faces being shaped to conform to the corresponding faces of the groove. The grips are each provided with a rectangular slot, g, a part of the slot being formed in each halfsection. The grips are also provided, one on its upper end and one on its lower end, with a shallow socket, g, centrally located in the end for the purpose which will hereinafter appear. Two levers, H, are each provided with a laterally-extending rectangulair-shaped lug, it, at its inner end, which lug is adapted to tit within the slot 9 in the grip. The said levers are slightly curved near their inner ends, and from thence extend outwardly to or beyond the outer ends of a pair of concentric arms, K. The arms K are loosely mounted on the forward end of the shaft A, and are provided at their outer ends with depending projections 7;, to the ends of which the above- (lescribed levers Hare pivotall y secured. The arms K are further provided with the bent auxiliary arms L, located near their pivotal support and extending laterally thereto, one upwardly and the other downwardly. The ends of the auxiliary arms L extend into the groove f a short distance above and below their respective grips, and said ends are pr0- vided with curved bars or rods 1'', rigidly secured thereto, the free ends of which engage the beforementioned shallow sockets g inthe ends of the grips G. The curved bars or rods Z are surrounded by coiled springs the tension of which is exerted against the ends of the grips, tending to force them off the ends of the curved bars Z. The arms K are each further provided with a series of perforations, M, through which the lower ends of the con neeting-rods E are pivotally secured thereto in the desired lateral adjustment, for regulating the stroke and changing the speed.

The operation of the device is as follows: Commencing with the slide D in elevated adjustment and considering the part of the device opposite the right hand of the person facing the front elevation thereof as the right of the device, and the opposite side as the left, and suppose the slide D to start on its downward movement, the downward pressure on the end of the right-hand lever H is opposed to the pressure of the spring on the right-hand curved bar Z, and the motion of the outer end of the said righthand lever H thereby anticipates the motion of the inner end of said lever, and hence of the grip G- attached thereto, whereby the rectangularshaped lug h in engagement within the slot in said grip is slightly rotated, causing the half-sections of said grip to separate and bind against the faces of the groove f. The said right-hand grip is thus locked to the wheel 1* and causes it to rotate therewith. At the same time the downward pressure on the end of the left-hand lever H is in the same direction with the pressure of the spring on the curved bar Z in engagement with the left-hand grip, and, as the auxiliary arm L rotates with the arm K, the tension of the spring is held constantly against the said grip; hence the downward motion of the outer end of thelefthand lever H does not anticipate the downward motion of the inner end thereof, the rectangular shaped lug h is not rotated, the half-sections of the grip are not separated,

and the grip slides freely downward in the *groovef. \Vhcn the slide D makes its upward stroke, the conditions of the two grips are reversed and the action is the same in principle as that just described. The lefthand grip is locked to the wheel F and righthand grip released, and the wheel continues its rotation in the same direction. The motion of the shaft A may be transmitted to a counter-shaft, A, through suitable multiplying-gears, O 0.

it is evident that slight changes may be made in the form and arrangement of the several parts described without departing from the spirit and scope of my inventionas, for example, other forms of spring than the coiled form shown might be used in connection with the auxiliary arms and grips, or the annular groove mightbe formed in the face of wheel F and grip caused to take laterally against its sides; hence I do not wish to be understood as limiting myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with agroovcd wheel suitably mounted, of a pair of two-part grips and means for operating the grips independent of each other, whereby they are alternately caused to bind against the opposite sides of the groove, substantially as set forth.

2. The combination, with a grooved wheel suitably mounted, of apair of sectional or two-part grips adapted to fit within the groove and means for alternately separating the gripsections and allowing them to collapse, substantially as set forth.

3. The combination, with a reciprocating slide and a wheel provided with an annular groove, of spring-actuated two-part grips adapted to fit within the groove, and independent devices connecting the slide and grips, whereby the latter are caused to alternately engage and release the sides of the groove, substantially as set forth.

4. The combination, with a reciprocating slide and a wheel provided with an annular groove, of a pair of spring-actuated grips, each grip made of two parts and adapted to fit within the groove, and a pair of grip-operating levers actuated by the slide and adapted to act in conjunction with the springs in causing the grips to alternately engage and release the sides of the groove, substantially as set forth. A

5. The combination, with a reciprocating slide, a grooved wheel suitably mounted, and a pair of grips adapted to fit within the groove of the said wheel, of a pair of grip-operating levers, a pair of concentric arms attached to said grip-operating levers and the slide, and a pair of auxiliary arms adapted to support springs in contact with the grip, substantially as set forth.

6. The combination, with a reciprocating slide and a wheel provided with an annular groove, of a pair of two-part grips adapted to lit within said groove, a pair-of concentric arms adapted to be connected with the slide in different lateral adjustments, and devices connecting the said arms and grips, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES H. TUOKNOOD.
